“…The proton conductivity of the hybrid membrane first increased and then decreased with the increase of the filler, which was due to the agglomeration of the added organic–inorganic filler and hindered the normal proton transport. The SPEEK/UNCS-3, studied by Long et al 97 demonstrated the highest proton conductivity of 186.4 mS cm −1 . UNCS acts as a bridge between the proton donor and acceptor, thereby reducing activation energy, shortening proton conduction distance, and consequently enhancing proton conductivity (Fig.…”

“…Metal–organic frameworks (MOFs) have received considerable concerns because of their adjustable pore composition and easy functionalization of the framework. Correlationally, they have broad applications in gas adsorption, proton conduction, catalysis, sensors, etc. Among them, the exploration of the proton conduction properties has triggered new attention in recent years. The modulability and modifiability of the structures for MOFs are extremely helpful in the optimization of proton transfer. Additionally, their crystallinity features, coupled with the intervention of subsequent controllable factors, will optimize the proton transport channel and give people a deeper understanding of the proton conduction mechanism.…”

“…The commercially available proton exchange membranes are manufactured by a series of nafion series membranes consisting of polytetrafluoroethylene main chains and perfluoroethylene ether side chains of sulphonic acid groups [18,19]. However, when the temperature is higher than 80⁰C the conductivity of these membranes starts to decrease pointedly and the preparation process of nafion membranes is complex [20]. Furthermore, the high cost of preparation and fuel crossover also limit their applications [21,22].…”
